Help! LMB bit off more than he can chew?

[boatsnhoes]

(hello fellow mfk'ers) im new to posting but not to the site or the hobby. anyway, gonna skip the introduction for now because im pretty concerned about my largemouth bass. I woke up this morning, and apparently my baby lmb (about 6 inches) decided it would be a good idea to eat one of the four shiners i was keeping in my tank (this shiner was about 4 inches). Now, i hear that lmb can fit basically any fish smaller than themselves in their mouths, but this just looks like too much. The tail of the shiner is out of his mouth, and i can clearly see the head of it in the bulge of the bass stomach. I've been keeping an eye on him for a few hours now, he is swimming around normally, and seems relatively ok, maybe breathing a bit more rapidly. worried about him choking or something. What should i do, if anything? please see the attached pictures.

Other information: (sorry, trying to cover everything)
Tank:55 gallon (temporary, he will be moved to a 125 shortly)

I feed him nearly every other day, about 20-40 ghost shrimp, or guppies.

He will swallow it.

You can try to scare him, go after him with a net as if you want to catch it. Chances are he'll spit the shiner

thanks, might try that if he starts looking worse. But i'd hate to strip him of his meal if he can eventually down it. I read somewhere that they have small teeth near their stomachs to help with digestion, that true?

Looks like he'll be fine, Im pretty sure if he has a problem hed spit it.
